‖ propodeon Entom.|prəʊˈpɒdiːən|
Improperly propodeum.
[mod.L. (Newman) f. Gr. πρό, pro-2 + ποδεών (-ῶνος) the neck or mouth of a wineskin, or of the bladder; hence, any narrow end.
(The Latinized form in -podeum was app. founded on the misconception that the Gr. word is a neuter in -ον.)]
That part of the thorax, principally in Hymenoptera, which precedes and partly surrounds the petiole; originally the first abdominal segment.
1833E. Newman in Entomol. Mag. I. 410 The fifth segment is the Propodeon, and is, of the whole thirteen, the most difficult to determine, because in orders of the same class it appears in different modes. 1895Camb. Nat. Hist. V. 491 [The term ‘Propodeum’] was proposed by Newman, under the form of propodeon, and appears to be on the whole the most suitable term for this part. 1899G. H. Carpenter Insects iv. 268 The partial or entire fusion of the first abdominal segment (propodeum) with the thorax. |
